THE EFFECT OF DIFFERENT PROPORTIONS OF MONITORED ELEMENTS ON OPERATOR PERFORMANCE IN A SIMULATED RADAR AIR TRAFFIC CONTROL SYSTEM

摘要

A simulated radar approach control system was utilized to evaluate the in¬fluence of different levels of monitoring on system performance. Monitoring level was varied by manipulating the proportion of aircraft in the system having air¬borne position information (API) equipment. The API-equipped aircraft did not require active control of their approach path as did those aircraft without such equipment.nFour conditions were compared:(a) 100%, (b) 63% (c) 37%, and (d) 0% of aircraft with API equipment. Eight laboratory-trained controllers participated. Results indicated an approximately linear increase in system performance as pro¬portion of API-equipped aircraft was increased. Recommendations for future utilization of API in terminal operations were considered.
